Answer:
It is possible to determine their functions and to identify the mechanism involved in their mode of inheritance
Explanation:
Matrilineal inheritance refers to the inheritance of genes directly from the mother, it either through the inheritance of mitochondrial DNA or by the epigenetic mechanism of genomic imprinting (in the case above indicated, maternal imprinting). By mutating genes which are inherited from the mother it is possible to study their functions as well as their mode of inheritance. By using a reverse genetics approach, many maternal imprinted genes have recently been identified to be involved in embryo development, especially in model organisms like <em>Drosophila</em>.
Answer:
ability to differentiate into other cell types during cell division i.e. totipotent nature
Explanation:
Stem cells are undifferentiated cells with the unique ability to develop into specialized cell types in the body during early life and growth through the process of cellular differentiation. When a stem cell divides, each new cell has the potential to either to remain a stem cell or become another type of cell with a more specialized function e.g muscle cell, red blood cell or a brain cell.
Stem cells provide new cells for the body as it grows, and replace specialized cells that are damaged or lost. This ability of stem cells to differentiate into a variety of cell types in an organism including embryonic tissue, is an important distinguishing factor. They have two unique properties that enable them do so:
1. They can divide over and over to produce new cells
2. As they divide, they can change into the other types of cell (cellular differentiation).
Answer:
A normal line
Explanation:
"In geometry, a normal is an object such as a line, ray, or vector that is perpendicular to a given object."
